Hi! Check out my other notices on McHales but I have the name Bridget in the 1881 census married toJohn Walmsley. It says she was born in Bolton and was aged 32. Her mother Mary was living with them in Blackburn Lancashire where I reside to this day.
Even if it is not the right person the name Bridget appears again in succeeding generations so it would seem to be a favourite of this clan from County Mayo.
